Pemdas
A
Parentheses Exponents Multiplication Division Addition Subtraction.
That’s the order Python follows as well.
The mistake people make with PEMDAS is to think this is a strict order, as in “Do P, then E, then M, then D, then A, then S.”
The actual order is you do the multiplication and division (M&D) in one step, from left to right, then you do the addition and subtraction in one step from left to right.
So, you could rewrite PEMDAS as PE(M&D)(A&S).
